This article devises a method to separate the Global Terrorism Database (GTD) into transnational and domestic terrorist incidents. This decomposition is essential for the understanding of some terrorism phenomena when the two types of terrorism are hypothesized to have different impacts. For example, transnational terrorism may have a greater adverse effect than domestic terrorism on economic growth. Moreover, the causes of the two types of terrorism may differ. Once the data are separated, we apply a calibration method to address some issues with GTD data — namely, the missing data for 1993 and different coding procedures used before 1998. In particular, we calibrate the GTD transnational terrorist incidents to ITERATE transnational terrorist incidents to address GTD's undercounting of incidents in much of the 1970s and its overcounting of incidents in much of the 1990s. Given our assumption that analogous errors characterize domestic terrorist events in GTD, we apply the same calibrations to adjust GTD domestic incidents. The second part of the article investigates the dynamic aspects of GTD domestic and transnational terrorist incidents, based on the calibrated data. Contemporaneous and lagged cross-correlations for the two types of terrorist incidents are computed for component time series involving casualties, deaths, assassinations, bombings, and armed attacks. We find a large cross-correlation between domestic and transnational terrorist incidents that persists over a number of periods. A key finding is that shocks to domestic terrorism result in persistent effects on transnational terrorism; however, the reverse is not true. This finding suggests that domestic terrorism can spill over to transnational terrorism, so that prime-target countries cannot ignore domestic terrorism abroad and may need to assist in curbing this homegrown terrorism.

'Crisis' is the defining word for our times and it likewise played a key role in defining the scope of government during the Roman Republic. This book is a comprehensive analysis of key incidents in the history of the Republic that can be characterized as crises, and the institutional response mechanisms that were employed by the governing apparatus to resolve them. Concentrating on military and other violent threats to the stability of the governing system, this book highlights both the strengths and weaknesses of the institutional framework that the Romans created. Looking at key historical moments, Gregory K. Golden considers how the Romans defined a crisis and what measures were taken to combat them, including declaring a state of emergency, suspending all non-war-related business, and instituting an emergency military draft, as well as resorting to rule by dictator in the early Republic.
